There is no built-in featrue to delete IP addresses from headers.
If this is for messages submitted on port 587 (submission) or 465
(smtps or submissions), then you can simply delete all Received:
message headers, because there shuold be only one.
master.cf:
submission .. .. .. .. .. .. .. smtpd
-o { header_checks = pcre:{{/^Received:/ IGNORE}} }
...other -o options...
submissions .. .. .. .. .. .. .. smtpd
-o { header_checks = pcre:{{/^Received:/ IGNORE}} }
...other -o options...
This is much simpler than some of the on-line discussions.
